ABSTRACT:
An improved air circulation system for a microwave oven having an improved air inlet for delivering ambient air to the microwave energy generating device. The air inlet is defined in part by a formed portion of the cabinet providing an air channel to the front and rear of the oven for subsequent flow to the generating device. A first portion of the delivered air is conducted to the oven space while a second portion of the air is heated by heat transfer association with the magnetron structure of the generating device. The heated air is subsequently divided into two paths. In one path, the heated air is directed through a suitable outlet to exteriorly of the cabinet. In the other path, the heated air is directed through an upper cavity portion of the heating space to a rear portion of the lower oven cavity. The heated air, together with the air delivered substantially directly from the generator space to the lower cavity, is discharged through a front, upper opening of the cabinet. The improved air flow provides improved efficiency and cooking operation of the oven device.
